PARIS (AFP) -- NATO partners argued Thursday over the alliance's worth after French President Emmanuel Macron said it was undergoing "brain death", prompting a fierce defense of the bloc from Germany, Canada and the U.S. while drawing praise from non-member Russia."What we are currently experiencing is the brain death of NATO," Macron told The Economist magazine in an interview published Thursday, ahead of a NATO summit next month.But German Chancellor Angela Merkel defended the 70-year-old military alliance as "indispensible" and said Macron's "sweeping judgments" were not "necessary".Addressing journalists by Merkel's side, NATO chief Jens Stoltenberg warned that a weakened transatlantic alliance could "divide Europe", while the U.S. Secretary of State, also in Germany, insisted NATO was "important, critical."In the interview, Macron decried a lack of coordination between Europe and the U.S. and lamented recent unilateral action in Syria by Turkey, a key member of the 70-year-old military alliance."You have no coordination whatsoever of strategic decision-making between the United States and its NATO allies. None," he said."You have an uncoordinated aggressive action by another NATO ally, Turkey, in an area where our interests are at stake," Macron added according to an English transcript released by The Economist.After talks with Stoltenberg in Berlin, Merkel said Macron "used drastic words, that is not my view of cooperation in NATO".She added: "I don't think that such sweeping judgments are necessary, even if we have problems and need to pull together", while insisting that "the transatlantic partnership is indispensible for us".Stoltenberg said any attempt to distance Europe from North America "risks not only to weaken the Alliance, the transatlantic bond, but also to divide Europe".For Macron, "strategically and politically, we need to recognise that we have a problem"."We should reassess the reality of what NATO is in light of the commitment of the United States," he warned, adding that: "In my opinion, Europe has the capacity to defend itself."Macron said it was crucial to seek rapprochement with Moscow, which regards NATO and its expansion into ex-Communist bloc states with huge suspicion given that the alliance was set up to counter the USSR.From Moscow, foreign ministry spokeswoman Maria Zakharova hailed Macron's "brain death" observation as "golden words... a precise definition of the current state of NATO".
